Hello,
I want to simulate with ADIsimPLL the ADF41020 circuit to generate a 12.25 GHz signal. I set the PFD at 50 MHz but there is an error given by ADIsimPLL as you can see here.
I really don't understand why it is not working. I think that the divider…
We are ready to design a optical PLL to lock the phase between two lasers. We get a beat signal which is the frequency difference between two lasers from a photodetector.We want to input this 9.2GHz beat signal to the RFin port of ADF41020 chip.
Quenstion…
Hi all,
I am trying the ADF41020 evaluation board with its on board 100MHz reference clock. I power up the board and connect to my PC. Then write to its registers via the ADI PLL Int-N program. The program shows that the board is connected. But when…
Dear all,
For our research at Texas A&M, we need to use high purity 16GHz for ADC testing. The ADF41020 evaluation board has the proper PLL chip which can go up to 18GHz, but the VCO used on this board can only produce up to ~13GHz. My question is…
My customer purchases the evaluation board EVAL-ADF41020 of the ADF41010 and checks the operation.
Customers are using Int-N PLL software.
The customer confirmed the output of about 11GHz - 12.8GHz.
After that, the customer attempted to sweep the frequency…
Hello. I would like to implement a fixed frequency generator of 12.2GHz using the ADF41020. In order to improve the in-band phase noise (within loop bandiwdth), I intend to use 50MHz phase detector frequency, using an external 100MHz Reference frequency…
I want to controll a EVAL-ADF41020 board using python. Does anyone have any example code using libusb or similar? Alternatively, do any of you know the communications protocol? Thanks for any advice or ideas.
I check the ADF41020, UG-405.
The value of same parts No. is different in the BOM and schematic.
Which value is correct, BOM or schematic ?
For example, following the value of C18,C19,C20,
